Rank

sage: E.rank()
 

The elliptic curves in class 30899.f have rank \(0\).

Modular form 30899.2.a.f

sage: E.q_eigenform(10)
 
\( q + 2q^{2} + q^{3} + 2q^{4} - q^{5} + 2q^{6} - 2q^{7} - 2q^{9} - 2q^{10} + q^{11} + 2q^{12} + 4q^{13} - 4q^{14} - q^{15} - 4q^{16} - 2q^{17} - 4q^{18} + O(q^{20}) \)

Isogeny matrix

sage: E.isogeny_class().matrix()
 

The \(i,j\) entry is the smallest degree of a cyclic isogeny between the \(i\)-th and \(j\)-th curve in the isogeny class, in the LMFDB numbering.

\(\left(\begin{array}{rrr} 1 & 5 & 25 \\ 5 & 1 & 5 \\ 25 & 5 & 1 \end{array}\right)\)

Isogeny graph

sage: E.isogeny_graph().plot(edge_labels=True)
 

The vertices are labelled with LMFDB labels.
